SPECIFICATION forming part of Letters Patent No. 301,760, dated July 8,1884.

Application filed January 3, 1884. (No model.) I

To all whom it may concern:

Be it known that I, EPHRAIM SEARS, acitizen of the United States, residing at North Salem, in the county of Guernsey and State of Ohio, have invented certain new and useful Improvements in Oowls, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to hoods to be used upon the tops of flues 0r chimneys, 'which shall change direction with the wind for giving directionto the draft of the flue, the construction and operation of which will be hereinafter more particularly set forth.

In the accompanying figure, which is a side elevation of my invention partly in section, A represents an ordinary chimney-top of any suitable material, and B represents a metallic pipe-section, which is secured upon it. To and aronnd the upper end of this pipesection is secured a cast-metal collar. 0, in the periphery of which is formed an annular groove, 0..

D represents the hood, the top of which is curved'and provided with a pointery E, of any suit-able construction. The lower portion of the hood is so formed that it will neatly, but not tightly, surround the collar 0, andis provided either with pins (1 d, (or pins with rollers upon them,) which take into the annular groove 0, and form bearingguides for the hood as it revolves or partially revolves with th changes of the wind. I

has a bearing'not only upon this rod G, but

also upon its pins which play in the groove c, but the pins d d servea particular purpose in holding the hood securely from any displacement from a vertical line. This hood acts, of course, as others do, revolving with the wind, cutting it off on one side, and directing the draft on the other. The hood may have side pieces, as usual, to more effectually direct the wind.

Having thus fully described my invention, what I claim is The combination, with the pipe, of the annularly-grooved collar secured to its upper end, the hood having its lower end adapted to fit over the collar, the anti-friction rollerbearings secured to the hood and playing in the groove in the collar, and the central up right standard secured to a cross-piece in the top of the pipe, and pivotally secured to the hood, and partially supporting the same, substantially as and for the purpose specified.

In testimony whereof I afiix my signature in presence of two witnesses.

EPHBAIM SEARS.
